In the powder coating process, the hanger is an indispensable tool, used to suspend the workpiece to be powder coated so that it can receive the powder coating evenly. However, traditional hangers have uneven force distribution when loading workpieces, resulting in uneven powder coating and failing to meet the user's needs. To address this problem, we propose a powder coating hanger assembly to solve the above-mentioned issues. Utility Model Content

The telescopic end of micro electric push rod 302 is precisely controlled by synchronous controller to operate synchronously, so that it passes through through hole 303 to push clamping plate 304 to move, thereby achieving reliable clamping of workpiece. The drive motor 501, through connecting rod 504 and cooperating with first bearing 502 and second bearing 503, can drive limiting plate 8 and fixed plate 1 to rotate smoothly. At the same time, the reinforcing bent rod 603 positions fixed plate 1 during rotation, avoiding the phenomenon of fixed plate 1 shifting, ensuring uniform rotation of workpiece, achieving uniform coverage of powder coating, and effectively solving the problem of uneven force on traditional hangers, resulting in poor powder coating effect.

[0023] The clamping mechanism 3 includes multiple mounting plates 301. The top of each mounting plate 301 is fixedly connected to the bottom surface of the fixed disk 1. Miniature electric push rods 302 are fixedly mounted on the sides of the three mounting plates 301 that are far apart from each other. Three openings 303 are provided on the outer surface of the positioning cylinder 2. The telescopic end of each miniature electric push rod 302 passes through the opening 303 and extends into the interior of the positioning cylinder 2. A clamping plate 304 is fixedly connected to the telescopic end of each miniature electric push rod 302. A positioning block 305 is fixedly connected to the side of each mounting plate 301 that is close to each other. The side of each positioning block 305 that is close to each other is fixedly connected to the outer surface of the positioning cylinder 2. The clamping mechanism 3 is mainly composed of multiple mounting plates 301, the tops of which are fixedly connected to the bottom surface of the fixed disk 1. A fixed connection is formed to create a stable support structure. On the outer surfaces of the three mounting plates 301, which are far apart from each other, a miniature electric push rod 302 is installed. These miniature electric push rods 302 serve as power sources to drive the clamping action. To ensure that the telescopic ends of the miniature electric push rods 302 can smoothly enter the interior of the positioning cylinder 2, three openings 303 are specially opened on the outer surface of the positioning cylinder 2. The telescopic end of each miniature electric push rod 302 extends through the corresponding opening 303 into the interior space of the positioning cylinder 2, and a clamping plate 304 is fixedly connected to its end. When the miniature electric push rods 302 work, the three clamping plates 304 can move synchronously to achieve precise clamping and positioning of the workpiece inside the positioning cylinder 2, which not only ensures the uniform distribution of clamping force but also ensures the stability of operation.

[0024] The drive mechanism 5 includes a drive motor 501. The bottom surface of the drive motor 501 is fixedly connected to the inner bottom wall of the mounting frame 4.

The top end of the connecting rod 504 is fixedly connected to the output end of the drive motor 501, and the bottom end of the connecting rod 504 is fixedly connected to the upper surface of the limiting plate 8. The drive mechanism 5 is mainly powered by the drive motor 501, which is fixedly mounted on the inner bottom wall of the mounting frame 4 to ensure stability during operation.

The top end of the connecting rod 504 is directly connected to the output shaft of the drive motor 501, and the bottom end is fixedly connected to the limiting disk 8, thereby transmitting the rotational power of the motor to the limiting disk 8. When the drive motor 501 starts, its output torque drives the limiting disk 8 to rotate through the connecting rod 504.

The inner ring of the connecting ring 12 is fixedly connected to the outer surface of the positioning cylinder 2. The connecting ring 12 is provided to reinforce the positioning cylinder 2 and ensure the stability of the positioning cylinder 2.

[0027] The working principle of this utility model is as follows:

[0028] In use, first connect the drive motor 501 and the miniature electric push rod 302 to the power supply and control them through the control switch. The extension and retraction end of the miniature electric push rod 302 is synchronously controlled by the synchronous controller. As the extension and retraction end of the miniature electric push rod 302 moves through the through-hole 303 and pushes the clamping plate 304, the workpiece can be fixed on the bottom surface of the fixed plate 1. Then, the drive motor 501 drives the limiting plate 8 and the fixed plate 1 to rotate through the cooperation of the connecting rod 504, the first bearing 502 and the second bearing 503. As the fixed plate 1 rotates, the reinforcing bending rod 603 can position the fixed plate 1 to ensure that the workpiece rotates evenly, thereby achieving the purpose of uniform powder coating of the workpiece.
